ELECTRIC LAM P.

SPECIFICATION forming part of Letters Patent No. 603,112, dated April26, 1898.

Application filed October 9, 1897. Serial No. 654,660. (No model.)

To all whom, it may concern:

Be it known that 1, DAVID MIsELL, a subject of the Queen of GreatBritain, and a resident of New York city, county of New York,

and State of New York, have invented certain new and useful Improvementsin Electrical Lamps, of which the following is a specification,reference being had to the accompanying drawings, forming a part there-ID of, in which similar letters of reference indicate correspondingparts.

This invention relates to electrical bicyclelamps; and it has for itsobject to provide a simple and improved electric lamp of this characterwhich will insure economy by providing against the unnecessary oraccidental use of the current and which will furthermore possessadvantages in point of direct contact, positive action, convenience,efiectiveness, adaptability, and general efficiency.

In the drawings, Figure l is a perspective view of a bicyclelampembodying my improvements. Figs. 2 and 3 are vertical transversesectional views. Figs. 4 and 5 are hori- 2 5 zontal sectional views.

Referring to the drawings, A designates a box or casing which ispreferably of rectangular form and may be constructed of any suitable oradapted material. The casing is provided with a hinged back B, whichwill serve the double purpose of permitting ex amination of the interiorand retaining the removable battery securely in position. This hingedback also enables the removal of the battery, when desired, forsubstitution or any other purpose. The hinged back is secured in closedposition by a suitable catch 0, of any adapted construction, and whenthe device is used as a bicycle-lamp the hinged back may carry suitableattaching devices, as at D, for mounting the lamp in position upon thebicycle.

E designates the battery, which is arranged to fit the interior of thebox or casing and 5 may be formed of any suitable number ofelectrically-connected cells. I preferably use a dry battery of anysuitable form, and the battery is not fixed or attached to the casing,but is simply fitted or set therein, so that it can be conveniently andreadily removed when desired.

The battery carries upon its inner or front face, preferably at about acentral point, a contact-plate f, which may be in the form of aprojecting spring-plate, as shown, adapted, when the battery is inposition, to project against the inner end or contact-point g of anincandescent-lamp bulb H, which is inserted through the front wall a ofthe casing and is surrounded bya suitable reflector I of any preferredconstruction. The lamp-bulb is preferably adjustable by means of athreaded connection, as at j, in the opening a in the front wall of thecasing, by which construction and arrangement it may be readily adjustedwith relation to the contact-spring f to insure its positive bearing inconnection therewith.

Extending upwardly from and in contact with the inner contact of thelamp-bulb is a conductor-plate K, which may be insulated within thecasing from the inclosed battery, which plate is connected with acontact pin or post Z, exteriorly projecting at the top a of the casing.The post .1 is preferably in its exterior form of a shape correspondingto tack-head or small flat knob.

M designates an arched handle, which is journaled in suitable bearings,as at n 72, upon the top of the casing. One of said bearings n isconnected by conductor 0 with a spring contact-plate P, arranged withinthe casing, preferably at one of the upper corners, and bowed, as shownat p. This spring contactplate P is adapted to bear against acontactplate q, arranged upon the inner or front face of the battery atone of its upper corners.

Upon the top of the casing are provided two bowed spring-plates 1' r,upon which bear gudgeons m m upon the ends of the handle, said gudgeonshaving square or angular sides, as at m m, by means of which relativeconstruction and arrangement the handle is retained by the tension ofsaid spring-plates either in a normal upright position or in ahorizontal position in contact with the post Z.

The spring contact-plate f is in connection with one pole of the batteryand also with the lamp, and from this connection the conductor K leadsto the contact pin or post Z. The contact-plate q is inconnection withthe other pole of the battery and in contact with the springcontact-plate P, from which extends the conductor or connection to thehandle. Therefore when the handle is in normal upright position thecircuit is broken; but when the handle is turned downinto horizontalposition, so that it bears against the contactwith the casing the lampmay be readily adjusted to regulate its contact with thespringplate f,as desired.

Bymeans of the rectangular face-gudgeons bearing upon the bowed springsthe handle is securely maintained in either of its two positions-thatis, either in its normal upright position, when the lampwill be out ofcircuit, or in a horizontal position in direct contact with the post Z,when the lamp will be in circuit. Any possible jarring or jolting of thehandle from direct and positive connection with the post [is thusobviated.

It will be understood that while my improved lamp is especially adaptedfor use as a bicycle-lamp it may be also effectivelyemployed as aphotographers lamp or for any other purpose in which a simple andconvenient lamp is desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An improved electric lamp, comprising a casing, a battery carriedthereby, a lamp in connection with one pole of said battery, a conductorextending from said connection to a contact conductor or post exteriorlyarranged upon the casing, a handle in connection With the other pole ofthe battery, and bowed spring-plates bearing with relation to the handleand operating to maintain it in either a normal upright position or inahorizontal position in contact with said pin or post, whereby thehandle operates to make or break the circuit and is held in positiveposition for both purposes, substantially as and for the purpose setforth.

2. An improved electric lamp, comprising a casing, a batteryarrangedtherein, a lamp in connection with one pole of said battery, a conductorextending from said connection to an exteriorly-arranged contact pin orpost. a handle journaled upon the casing and in connection with theother pole of the battery, said handle having rectangular-facedgudgeons, and bowed spring-plates bearing with relation to saidgudgeons, whereby the ban dle is positively maintained in either normalupright position or in horizontal position in contact with the pin orpost and serves to either make or break the circuit, substantially asand for the purpose set forth.

- 3. An improved electric lamp, comprising a casing, a battery carriedthereby, an exteriorly-arranged contact pin or post in connection withone pole of said battery, and a lamp comprised in the circuit, incombination with a journaled handle in connection with the other pole ofthe battery, and means for retaining said handle in either normalupright position or in horizontal position in contact with said pin orpost, whereby the circuit is automatically maintained in either openedor closed condition by the fixed position of the handle, substantiallyas and for the purpose set forth.

4- An improved electric lamp, comprising a casing, a battery carriedthereby, an exteriorly-arranged contact pin or post in connection withone pole of the battery, andalamp comprised inthe circuit, incombination with a journaled handle in connection with the other poleofthe battery, said handle adapted to be brought into contactwith said pinor post, and spring devices for locking the handle in said contactposition, whereby the handle serves as an automatic ci rcuit-maker,substantiall y as and for the purpose set forth.

5. An improved electric lamp, comprising a casing, a battery carriedthereby, a lamp in connection with one of the poles of said battery, abowed-sprin g contact-plate in connection with the other pole of thebattery, and a handle in operative connection with the lamp and saidspring contact-plate,whereby a positive circuit connection againstjarring or jolting is provided, substantially as and for the purpose setforth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 5th day of October, 1897.

DAVID MISELL.
